Material examined. CHINA: 2♁♁ ( CZHQ) , Sichuan Province, Ya-an City, Yingjing County [ẾḦB], Daxiangling [kffiṅ], alt. 1400 m, VI.2015, Huang-Shun Xi leg.; 4♁♁, 1♀ ( CZHQ) , Sichuan Province, Leshan City, Mabian County [ḢŮB], Yonghong Town [AEIJØ], Dafengding Nature Reserve [kṃữbẍOiḞffl], alt. 1500 m, 12.VII.2022, Yuan Li leg.; 1♁ ( CRXS) , Sichuan Province, Emeishan City, Emeishan [Ẃ眉Ɯ], Wanfoding [hdzữ], alt. 3099 m, 1.VIII.2022, Tian-Xuan Gu leg.

Distribution. China (Sichuan).

Remarks. Recently, we examined a small sized particular specimen of L. boileaui ( Fig. 12A–B ) from Emeishan, Sichuan Province, China, which is indistinguishable from the holotype of L. bidentis on external characters (see fig. 2 in Schenk, 2013). Thus, we propose L. bidentis as a new synonymy for L. boileaui . In addition, because the unreasonable distribution of the location that in the Southeastern Vietnam is far from the other species distribution ranges of the same species-group, and it seems that no more individuals of the species have been found in Vietnam since 2013, we wonder it may be a wrong distribution data.
